Yee-haw!

Cloud's DLC costume is from Kingdom Hearts, and Lightning's DLC costume is Aya Brea's 3rd Birthday default attire (Aya can also wear Lightning's Final Fantasy XIII attire as an alternate outfit in The 3rd Birthday).

Cloud's default outfit has been redesigned to fit the Amano artwork, and Tifa has her classic Final Fantasy VII attire as her default outfit, along with her Advent Children attire as an alternate outfit. I've been waiting a long time to see what Tifa would look like using today's game engine while wearing her classic attire.
